Fix partitioning for trx_id-versioned tables. `partition by hash`, `range` and others now work. `partition by system_time` is forbidden. Currently we cannot use row_start and row_end in `partition by`, because insertion of versioned field is done by engine's handler, as well as row_start/row_end's value set up, which is a transaction id -- so it's also forbidden. The drawback is that it's now impossible to use `partition by key()` without parameters for such tables, because it references row_start and row_end implicitly. * add handler::vers_can_native() * drop Table_scope_and_contents_source_st::vers_native() * drop partition_element::find_engine_flag as unused * forbid versioning partitioning for trx_id as not supported * adopt vers tests for trx_id partitioning * forbid any row_end referencing in `partition by` clauses, including implicit `by key()`
